Medina, Some of the specimens afterwards collected bj Berlandicr (distributed as Nos. 2502 



and 2573) connect tlils with the variety Drummondii, (Centauridiiira Drummondii^ Torr. d: 

 Gray^ which has acute or cuspidate involucral pcales. 



Grindelia squarrosa^ Dunal,; var. graxdiflora, Oray^ PL IVrifjIity 1, p. 98, etc. On i\\^ 

 Manzanal, Texas, etc. It is No. 1921 of Berlandier's collection, 



Grindklia lanceolata, Null.; Torr. d: Gray^ I. c. Gobre, New Mexico; Thurler^ Blgeloio. 

 Probably a mere variety of G. squarrosa. 



Grixdelia arguta, Schrader^ in DO. L c. Gobre caiion ; Wrijht, Thurber. Probably this is 

 likewise G. squarrosa. 



Grindelia inuloides, IFilld.; var. MiCRocErnALA. G. microcephala, DG. Prodr. Southern 

 and western Texas; Schott^ Parry. This is the same as Berlandier's plant, (No, 2057,) on 

 which De Candolle founded his G. microcephala. The achenia are of the same sliape as in G. 

 inuloides ; but their thick walls are generally smooth and even, yet some of them show traces 

 of the corky-rugose character of those of genuine G. inuloides.

San Luis Key; February. Var. y. capitulis multo 

 minoribus ; involucri squamis plerumque obtusis ; ligulis 7-10, — Cordilleras, near San Felipe, 

 California, on the eastern slope ; June. The first variety is a strong vernal form, with larger 

 heads than in ray specimens from Nuttall, yet agreeing very well with his description. The 

 second is a later, much branched state, I believe, of the same species, although the heads are 

 only one-third as large, the rays and the involucral scales proportionally fewer, and the latter 

 either obtuse or retuse, or merely mucronate. The pappus of this occasioaally consists of 6 or 

 8 bristles. The comparison of both forms with Nuttall's original specimens shows that they all 

 belong to one species.

 Texas ; ScJiott. 



IIeierotheca scabra, DC; Torr. & Gray^ I. c- San Antonio to Presidio del Norte, etc.; 

 Bigelow^ Scholt^ Pay^ry. Very tall specimens were gathered at Presidio by Dr. Bigelow, 

 growing four feet high. 



Heterotheca floribunda, Benih. Bot. Voy. Sulph, p. 24. San Luis Ptey, California; October; 

 Parry. This is certainly Bentham's H. floribunda, and is the same as No. 275 of Coulter's 



a collection, although the heads are somewhat larger. I fear it passes into H, grandi-
